Iberdrola is set to enhance Spain’s energy storage capabilities by installing six BESS installations with a total capacity of 150MW.

The projects will be located across Castilla y León, Extremadura, Castilla La Mancha and Andalusia and will help integrate renewable energy into the national grid.

Each of the six batteries will have a power output of 25MW and a storage capacity of 50 megawatt-hours.

They will use lithium-ion technology, known for its efficiency, maturity and cost-effectiveness.

The BESS installations will operate as hybrid systems, paired with solar energy sources, allowing both the photovoltaic plant and the battery to share the same connection point.

The projects have been recognised as Strategic Projects for Economic Recovery and Transformation within the country’s renewable energy, green hydrogen and storage division.

In Castilla y León, the Revilla Vallejera site in Burgos, where the company inaugurated its first hybrid wind-solar plant in 2023, will see the installation of one of the batteries.

Extremadura will receive two batteries, both located in the province of Cáceres, next to the existing C Arañuelo I and II photovoltaic plants.

Castilla La Mancha will also host two batteries in the municipalities of Valverdejo in Alarcón and Olmedilla de Alarcón in Cuenca, where Iberdrola already operates solar parks.

The final battery project will be constructed in Huelva, in the municipality of Puebla de Guzmán, home to the Andévalo photovoltaic plant.

In June 2023, Iberdrola secured a loan of €1bn ($1.08bn) from the European Investment Bank to support energy transition in Europe.

The company plans to build a network of 19 solar plants and three onshore wind farms across Spain, Portugal and Germany.
